Answer:
Heat flows from hot to cold objects. When a hot and a cold body are in thermal contact, they exchange heat energy until they reach thermal equilibrium, with the hot body cooling down and the cold body warming up. This is a natural phenomenon we experience all the time.
Explanation:
Volumetric flasks are most accurate
Answer:
mass of the products
Explanation:
The law of conservation of mass states that mass in an isolated system is neither created nor destroyed by chemical reactions or physical transformations. According to the law of conservation of mass, the <u>mass of the products </u>in a chemical reaction must equal the mass of the reactants.
Hence the period is 1 sec.
<u>Explanation</u>:
- If the time taken by a single pendulum is 0.25 seconds. Then a pendulum will move to two extreme positions from one mean position only. That will means that the total time period is given by
T = 2 
0.25 = 0.50 seconds.
- A pendulum will oscillate from mean to the extreme, then extreme to mean, then mean to the extreme and again extreme to mean, so it will cover 2 cycles.
Hence, 2 0.50 = 1.
